What is quantum cryptography?

"Scientists are examining quantum cryptography (QC) as a possible alternative to traditional encryption technologies. But how practical is QC outside the laboratory?

Physicists investigating the fundamental processes of the universe may have found the key (pardon the pun) to the future of cryptography. By applying the principles of quantum mechanics--the laws governing how the subatomic universe works--to the needs of cryptography, researchers are finding that the manipulation of light may be the strongest form of encryption devised to date."

I found this introduction in the article at the following link. I think it's a good initial description.
